Remove InfiniBand Switch Cards

To remove an InfiniBand switch card from the Topspin 360 chassis, perform the following steps:
1. Make sure the Topspin 360 chassis is secure.
2. If you are removing the InfiniBand card in slot 16 (the bottom card), you must power down the
chassis before removing the card. The InfiniBand card in slot 16 is not hot-swappable.
The InfiniBand card in slot 15 is hot-swappable as long as there is a functional card installed in slot
16.
3. Properly ground yourself to avoid potential electrostatic discharge and damage to the card.
4. Facing the back of the Topspin 360 chassis, unfasten both screws on the InfiniBand switch card.
Do not attempt to remove the screws from the card. Just unscrew them until you are sure the card is
no longer attached to the chassis.
5. Open both ejector levers simultaneously and pull the switch card toward you.
6. Install blanking panel into the empty chassis bay to ensure appropriate cooling.
